[Announcement] I will be giving 20-minute talk titled
"Equationeering With BARS" on Tuesday, 12 February 2013,
at 4:30pm in room SL-111 at Scottsdale Community College.
This talk is being given as part of SCC's participation
in the Arizona SciTech Festival. Prerequisites: None. This
talk is free and open to the public (no registration required).

[Update] This talk was given on 12 February 2013
and the talk worked. I am hoping to give this talk again.

BARS were started as part of a Learning About Math resource that has
a road tripping theme.

A road sign becomes a BARS when the numbers
in the sign are used to find an equation. In a nutshell, each number
in the sign must be used and each number can be used only once.
When searching for equations, math functions can be used on the
numbers found in a sign (e.g. sqrt(n), cuberoot(n), log(n),
factorial(n)). In addition, equations can be rsEvals,
which are when the numbers in a sign are used in expressions that
evaluate to "special" numbers (e.g. an approximation of
Pi, Phi, 37, 42, state numbers, highway numbers, etc.).
